TRIMMING OUTBOARD “DOWN” (“IN”)
WARNING
Excessive speed at minimum trim “In” may cause undesirable and/or unsafe steer-
ing conditions. Each boat should be tested for handling characteristics after any
adjustment is made to the tilt angle (tilt pin relocation).
• Will help planing off, particularly with a heavy load.
• Usually improves ride in choppy water.
• In excess, can cause boat to veer to the left or right (bow steer).
• Transfers steering torque harder to right (or less to the left).
• Improves planing speed acceleration (by moving tilt pin one hole closer to transom).
Operating “Down” circuit will actuate the “down” relay (located under engine cowl) and close
the electric motor circuit (motor will run in opposite direction of the “Up” circuit). The electric
motor will drive the pump, thus forcing automatic transmission fluid through internal pas-
sageways into the “down” side of the trim cylinder. The trim rod will move the engine down-
ward to the desired angle.
Trailering Outboard
WARNING
Excessive engine trim angle will result in insufficient water supply to water pump
causing water pump and/or powerhead overheating damage. Make sure that water
level is above gear housing water intake holes whenever engine is running.
While operating “up” circuit, the cylinder rod will continue to tilt the outboard to a full up posi-
tion for trailering.
Tilting Outboard Up and Down Manually
WARNING
Before loosening the manual release valve, make sure all persons are clear of en-
gine, as engine will drop to full “down” position when valve is loosened.
With power trim installed, the outboard can be raised or lowered manually by opening the
manual release valve 3 to 4 turns (counterclockwise).
